Recall 25V567 covers 59 2020, 2021, 2023, 2024, and 2025 Mci electric buses with overheating battery modules. Dealer repair will be free once available.
Mci is recalling 59 2020, 2021, 2023, 2024, 2025 D45CRTELE, J4500E, and D45CRTE buses because an inadequate high-voltage battery busbar weld and incorrect software can overheat the battery module. An overheated module increases the risk of fire, and Mci dealers will complete the repair free of charge once it is available.

What's wrong?
The high voltage battery module in these Mci buses stores the electrical power that drives the traction motor. Inside the module, a busbar and J-bar weld carry current between battery components, while battery-management software watches the pack and is supposed to stop unsafe current flow when a fault is detected. The affected buses use Freudenberg battery modules.
On affected modules, the J-bar weld was not made deeply enough. Over time, that weak weld can separate, creating localized arcing, which means electricity jumps across a small gap instead of flowing through a solid connection. That arcing builds heat at the weld location and damages a nearby cell. The software also fails to stop current through the pack when this condition is detected, allowing the overheating condition to continue.
The warning sign listed for this recall is a battery fault message: "High Voltage Line Open / Fuse Blown String X." Treat that message as a traction-battery fault, not a routine service reminder.

What's the safety risk?
An overheating battery module increases the risk of a fire. If a high voltage battery warning appears, stop using the coach and call the dealer for guidance. The recall repair is not open yet, so ask the dealer what to do until inspection, module replacement, and software update are available. Repair will be free at any franchised Mci dealer once available.
What should I do?
- Check your VIN to confirm your 2020, 2021, 2023, 2024, 2025 Mci D45CRTELE, J4500E, or D45CRTE bus is included in this recall.
- Wait for Mci's remedy instructions before scheduling; owner letters were mailed October 6, 2025.
- Contact a franchised Mci dealer once the remedy opens to schedule the free battery-module inspection or replacement and BMS software update that addresses battery overheating.
- Bring the owner letter if you have it, and reference recall number 25V567 when you call.
- Call Mci customer service at 1-800-241-2947 with questions about interim guidance or repair timing.
What happens at the repair
Once Mci opens the final repair, a Mci technician will inspect the high voltage battery module, replace the module when needed, and update the BMS software. The final dealer repair will be free once available. Owner letters were mailed October 6, 2025, so contact Mci customer service or your dealer for current repair status. Mci used its general reimbursement plan on file. If you already paid for a related battery module or BMS repair, ask Mci how to submit documented expenses under that plan.

Frequently asked questions
What is recall 25V567?
Recall 25V567 covers 59 Mci D45CRTELE, J4500E, and D45CRTE buses with a high-voltage battery issue. An inadequate busbar weld and incorrect battery management software can let a battery module overheat, increasing fire risk. Mci's recall plan calls for inspection, battery module replacement as needed, and a BMS software update.
What should I do if my 2020, 2021, 2023, 2024, 2025 Mci D45CRTELE, J4500E, or D45CRTE is on this recall?
Check your VIN to confirm your specific bus is included in recall 25V567. If it is, contact a franchised Mci dealer or Mci customer service at 1-800-241-2947 and ask whether the battery inspection, needed module replacement, and BMS software update are open for your VIN.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to perform the safety recall repair at no cost. Mci's remedy includes inspection, battery module replacement as needed, and a BMS software update. Parts and labor are covered once the repair is open for your VIN.
What is the safety risk?
The safety risk is fire. Mci reported that an inadequate weld on the high-voltage battery busbar and incorrect software can cause a battery module to overheat. If your VIN is included, ask Mci or the dealer for current operating guidance before the repair is completed.
When were owners notified about recall 25V567?
Mci mailed owner notification letters on October 6, 2025. A mailed letter is helpful, but the VIN still decides whether this recall applies to a specific bus. Used, transferred, or fleet vehicles need a VIN check even when no letter arrived.
